Sun's Grid Computing Approach

● A flexible and scalable architecture– Pools computing resources to solve important

problems– Collects unused capacity for better utilization– Architecture for seamless addition of resources– Up to hundreds or thousands of processors and

systems

● Multi-platform, Multi-OS● Distributed resource management (DRM)● Distributed system and software

Resources

Per Host● load_avg● mem_free● OS/patch-level

Global● floating licenses● shared storage

● job resource request: job A needs 1 license and 1GB● Load/suspend thresholds: suspend jobs if load_avg > 1.5● load formulas: send jobs to hosts with least load; out of those, choose hosts with most free memory

Resources used for

THE HEART OF GRID ENGINE MANAGEMENT

Built-in and custom resources● Static resources: strings, numbers, boolean● Countable resources: eg, licenses, MB of memory/disk● Measured resources: value provided through Load Sensor

Integrating applications with Grid Engine

1) Unmodified/legacy application binaries:integrate using wrapper script

2) Interactive applications: use pluggable remote mechanisms, eg, ssh, rsh, telnettwo most common approaches

3) Grid-ready applications: modify code touse DRM APIsAPI recently standardized

4) Java applications: JGrid package for low-level coupling (object/method distribution)currently provided separately

N1GE 6 New FeaturesScheduler Functionality

– Advanced planning capabilities● Resource Reservation w/ Backfilling● Can reserve any resource, eg

memory, CPU, license– More sophisticated scheduling

algorithms● Management policies matched with

business priorities:– Priority, urgency, share tree,

category, deadline, etc

Policies for Job Prioritization

Priority determines which pending jobs get dispatchedJob priority calculated based on three sub-policies (normalized to 0.0 < N < 1.0):

prio = Wurg Nurg + Wtix Ntix + Wpsx Npsx

Nurg = normalized UrgencyNtix = normalized TicketsNpsx = normalized PosixW = weighting factors

N1GE 6 New FeaturesAnalysis / Monitoring / Accounting● Value-add module for doing

analysis, monitoring, accounting reports, etc.– Fine-grained resource recording– Stored in RDBMS in well-defined schema– provides built-in capability for reporting,

chargeback, etc– Web-based console tool provided for

generating reports, queries, etc.

38

Why 2nd separated DB?● Different access considerations

– Standardized access (SQL, ODBC, JDBC)– More powerful database structure

● Independent of core system data– historical data– Derived data (sums, averages ...)– queries won't affect system

performance– lower requirements on availability

39

Architecture

● Reporting-Writer:Java application

● loosely coupled to the SGE system via qmaster-generated reporting file

● Stores raw data,pre-processed data to SQL-DB via JDBC

Stored Data● Job related information

41

ARCo: Accounting and Reporting Console● Web-based tool for displaying data

in reporting DB● Based on Sun Web Console● Ability to create simple and

advanced (SQL-based) queries● Generates tables, graphs,

exportable as CVS, PDF● Also, command-line report
